The three-time world champion was 11-5 up and just two frames away from victory when Monday's afternoon session got underway.
Higgins finished the job with little hassle, as breaks of 62 and 90 helped the 46-year-old to a 13-7 victory at the Crucible in Sheffield.
Looking back at the match, the Scot said: "Last night was massive for me, winning that session 7-1. You've got one foot in the quarter-final, but you've got to stay as professional as you can and get those extra frames to get in there."
Next up for the Higgins is a clash against the winner of a tightly-contested second round encounter between Jack Lisowski and tournament favourite, Neil Robertson.
Lisowski currently holds a 9-7 lead going into Monday's evening session, with Higgins admitting that both players present a serious challenge at the tournament.
When asked about the prospect of facing Robertson - the current world number three - Higgins said: "There'll be pressure on him because he's the tournament favourite and a hell of a lot of people are expecting him to win the world title - rightly so after the season he's had."
Higgins and Robertson clashed earlier this month in the Tour Championship final, with the Australian coming back from 9-4 down to win 10-9.
The Scot added: "He'll obviously start strong favourite, so I've just got to try and get in there and compete with him the same way I did in the Tour Championship and not wilt at the end of the line. I look forward at getting another crack at him."
Higgins could also face Lisowski who is looking to make it past the second round of the tournament for the first time in his career.
"Lisowski brings a different challenge," said the Scot. "He's got the chance to write his own chapter in this tournament. For him to beat someone as good as Neil - he'll be feeling on top of the world.
"He'll be feeling, if he can beat Neil Robertson, he can certainly beat anybody. That then makes him a dangerous animal."
Higgins' 16th quarter-final appearance at the Crucible will begin on Tuesday afternoon.
